Help My Father Recover from Lung Infection and Cardiac Arrest!

Susanta Sinha is my  Father. Susanta Sinha lives in West Bengal with his family. Our father suddenly got sick and we had to admit to the hospital. 

The doctors immediately identified that he is falling short of breath and had to put under ventilation. He had to undergo several tests, xrays and scans and is still in process of doing so. He has been diagnosed with Lung Infection and had a Cardiac arrest a couple of days back.
He is under ventilation from past one week and is showing improvement. He has to undergo treatment for his lungs and heart but only once he is stable and comes out of ventilation. The cost in hospital is rising and our family is not able to arrange money. We have spent whatever we have, took loan from friends and family, used whatever money we had and now we do not have money left for his treatment. 

The doctor said he needs to be in ventilation for next few days so that he gets stabled and then they will shift him to ICU and start treatment. 

We would not be able to continue the treatment or the stay in hospital and hence reaching out for help. Till now we have spent close to Rs. 400000 

We request you to help us save our father. He will survive and will undergo treatment only if we receive help. Whatever help is possible, kindly extend it to us. We would be ever grateful.
